Maslow insisted on psychology that emphasized

B) mechanistic and deterministic reactions of the individual.
C) conditioned responses and behaviorism.
D) human strengths, free-will, and the fulfillment of human potential.

Maslow's theory of self-actualization emphasized the importance of human strengths, free-will, and the fulfillment of human potential. He believed in studying human behavior in a holistic and subjective manner rather than mechanistically and deterministically. He also critiqued the narrowness of behaviorism and advocated for a more positive psychology that focused on individual growth and self-fulfillment.
